So I'm bringing this back up since we've had more time with 1.2. What do people think of the Jackson now?
From my experience, the unit likely needs to be toned down against medium tanks a little more and possibly go to 560 health, which is in discussion behind the scenes. Yes that means it'd go back to getting 2-hitted by Jagdtigers and Elefants and require less to kill from non-160 sources.
What is going to happen with those changes:
The initial problem of JT and Ele being uncounterable, especially for USF won't be fixed. The Jackson will become too valuable to be actually used for flanking. The Jackson will be stronger against anything that's not a JT/Ele/JP4.
You either allow more diverse counterplay for JT/Ele as ally (especially USF) or you will most likely see axis rely even more on tank destroyers.
I believe Barton suggested to have their range set to 60. Why not use that and keep the damage of 320. Then, those tanks will actually have their advantages but also an actual weakpoint. They will no longer be able inflict damage without exposing them to the enemy. USF would no longer have to fear their tanks being picked off from longer distances...
